IPC: F25B41/00
Filed: 2000-07-13
Abstract: PURPOSE: A muffler of an air conditioner is provided to prevent noise due to collision of refrigerant to a muffler pipe from being transferred to a room of a vehicle. CONSTITUTION: An intake pipe(29) is communicated with the upper part of a muffler pipe(30) to fill a first chamber(F) of the muffler pipe with refrigerant from an evaporator. The intake pipe is welded with the muffler pipe to prevent refrigerant from being leaked. An inserting hole(31) is formed at the bottom of the muffler pipe to accept an exhaust pipe(33). A second chamber(S) is communicated with the lower part of the muffler pipe, and an oil discharge port(34) is formed to discharge oil to the second chamber. If refrigerant flows into the first chamber through the intake pipe, the flow speed of refrigerant is reduced by a sectional area of the muffler pipe larger than one of the intake pipe. Thereby, the refrigerant collides with the inside of the muffler pipe to generate noise. The refrigerant noise is primarily absorbed by the double structure of the muffler pipe and a housing(32). Then, the noise is secondarily offset by oil in the second chamber. The noise is not delivered to a room of a vehicle.
